My invention can be-ap lied to a vehicle wheel of any type. In tiiedrawings it is shown a plied to one wheel, t of a wooden ielly 1, andmetal rim member 2. The rim member 2 is shownas ofawje'llknown type,having the downwardly and in- To all whomit 'may concern:

ment in Antisli ping Devices for Tires; and I do hereby dec are thefollowing to befa full, clear, and exactdescription thereof.

' This invention relates to means for preventingV the 'sli ing ofwheels"l of motor vehicles and theliike, and its object is tov providean'arrangement of chains for this urpose which will prevent the vwheelom slipping both 'under the driving Vforce of the motor and alsosidewise in rounding corners and the like. A y

A further object is to provide an arrangement of chains which is cheapin its original cost, not liable to derangement or breakage, and whichcan be easily taken E and repaired at a minimum cost and with a minimumamount of labor. j #Many priorv devices comprising' arrangements ofchains Jfor overcomingrthe slipping of the 'wheels of motor vehicleshave been devised, but most of these have been rather complicated,v andhave either been liable to deran ement or breakage' or else have been ofsuc `-a nature that they are expensive to repair in case of breakage orwhen'worn out, one serious difficulty being that they are so constructedthat they can 'be repaired only f by a skilled mechanic. l i' Thisinvention is intended to overcome the foregoing difhculties, and itconsists in thearrangement 'of chains and fastening meanshereinafterfdescribed, and particular y in an arrangement 'which permitsthe 4use of an ordinary standard chain for the treadpcn' 40 tion, andheld in place in such a manner that it can be readily appliedor taken 0Hby any vIn the accompanying drawings,v Figure 1 is a side view of aportion ofaivehiele wheel showing my invention applied thereto', Fig. 2is a cross section ,through thefelly, metal rim member and tire ,'Fig. 3a similar cross sectionshowing a modiiication; Fig. 4 1 is a side viewof the same; Figs. 5 and 6 are detailed views showing anothermodifieation; Fig. 7 is a perspective view of the hook 12. brace; andFig. 8 is a detail view oi one of. One or both'o the brace members 9 maythehook's. f be provided, if desired, with a lug 'or stud 19 the metalrim member shown of the split pneumatic type.

Secured to the rim at intervals are chain attaching means, bolts 5whichextend through the elly 1, and atene end being provided with ahead 6,and at their opposite. ends being threaded for. receiving the fasteningvpin 8. These bolts pass through suitable racing members 9 Aon each saidv`bracing members comprisng a curved vinclined bottom web 10,v adaptedto engage the curved side portions of the metal rim :member 2, andstiiienin and stren thening side webs 11. These lgnrace. members areclamped against the side faces of the felly between the head 6 andnut 7,and serve not only as washers or wearing members for the bolts 5, butals'o prevent the'felly from sli ping sidewise on the metal rim member,the latter function being secured by reason 'of the curved `lower facesof these brace members. engaging the curved vinclined side portions 3 ofthe metal rim member 2, as will be readily apparent. K'These securingbolts at one end are provided with suitable attaching means, shown in Fis. 1 to 4, as a hook 12, which is engaged by a link 13, which extendsoutwardly, and is curved so as to pass over theedge ofA the metal rimmember 2, said link in turn having `connected thereto-a short pieceA ofchain 14. In Figs. 5- and 6, vI have shown a modiication in which inplaceof the 'open hook 12, l.the

n 12a, which is engaged by a pin 15 f a clevis the side webs 11 of .thebrace member 9 extended and provided with o receiving a cotter pin 18,or ot er similar means which prevents the' link 13 from 'becoming'.accidentally disengagedA from the form of motor vehicle.

said means com risingside of the telly;l

bolt is provided with an eye .or closed 'hook ening's for esamecomprising a rim composed wardlycurve edge portions 3. Applied to 2 isatire 4.whic'h is` nut 7 andcotter 16 on the chain 14. Figs. 3, 4 .and7show any Vhardware store. length, extending entirely around tlie'wheelto enter a. suitable depression or recess in the metal rim member 2,said lug serving as an additional means to prevent side-v wisc movementof the felly on the metal rim member. The hooks 12 or eyes 12, 'andshort chain sections 14, are arranged alter-4 nately on the oppositesides of the wheel rim, and consequently in staggered relation toV eachother, as shown in Fig. 1. Each of the chain members 14 extendsoutwardly close to the tread of the tire 4, and terminates in a suitablehook for engaging the chain member 20, which lies on the tread portion Iof the wheel and is ,the part of the antislipping device which receivesthe wear. This chain 20 may be a standard chain of any suitable type,such as can be bought in in vazigza course, being attached alternatelyto t e hooks on the chain members 14 on the opposite sides of thcwheel.. All of the hooks, except one, are single hooks 21 such as'shownin Fig. 8, these being arranged to hook into a link of Vthec'liain 20.One of the hooks, however7 is double, as shown at 22, this being placedto receive tlie ends of the chain 20. All of these hooks "'liave,contracted openings to prevent the a wearandcannot be easily. broken.

chain 20 from becoming accidentally disengaged. If desired, a retaininglink. 23 maybbe attached to the hook, and pass over the end of the.hook, the latter being formed of spring metal, and having a slightoutward curve at its end to hold said retaining 4link in place.

The chain member 20 is 'the part which receives the wear, andpreferablythis is a heavier chain than the connecting chains 14. This chain member20 is so secured in placev that it can be readily replaced and'removedin; case of breakage, and by an unskilled person.. This is accomplishedby connecting one end of the chain links to one member of the doublehook 22, and then 1'assing saidv across the' of the'metal rim member 2,and the links 18,

are practically the only parts which receive anyhard blows from curbs,'cobbles or4 the like, but obviously these are not readily liable tofracture. The entire 'equipment contains no part which is liable to workloose. The

It 'is a continuous This. Work can beV4 nuts 7 can be of any well`knownlocked type, or may be held against lcoming off by any of the well knownmeans, such as the cotter pins 8. lf desired I the tire may be protectedfrom the chain byab'and ofleather or the like placed over the tread ofthe tire and fastened to the' hooks.

What I claim is:

1. An anti-slipping device for tires cornprising in combination, aseries of securing `means on the rim arranged alternately o'n o positesides and in staggered relation, a cfiain member connected to each ofsaid securing means and extending 'outwardly beyond the rim and endingin a hook, anda continuous chain extending in zigzag Imanner over thektire face and having links thereof engaging said several hooks. i
